This study was to evaluate the protective effect of vitamin E against long and short-term stress in ICR mice. Two groups which had been bred for 5 months (equivalent to human beings aged 20) were treated by immobilization stress for 8 weeks with or without vitamin E, and one out of two groups was continuously bred until they become 18 months old (equivalent to human senescence) with or without Vitamin E. Afterwards, the changes of serum and hepatic metabolites were investigated on the basis of the index of stress-related in vivo oxidative damage. As a result, it was found that stress increases serum triacylglycerol and aspartate aminotransferase (AST) in the long and short-term, and decreases serum HDL-cholesterol. In addition, stress concerned the decrease of total antioxidant status (TAS) and superoxide dismutase (SOD) as well as the increase of malondialdehyde (MDA) in liver. These results suggest that stress in one’s youth causes negative results in TG, HDL-cholesterol, AST, TAS, SOD and MDA measured in one’s senescent. The administration of vitamin E in the stressed mice decreases serum TG and AST that are increased by stress, and exerts influence on the increase of serum HDL-cholesterol. Also vitamin E recovered the values of liver TAS, SOD and MDA in the stressed mice. In conclusion, vitamin E represented protective effect in the stressed mice to some degree.

Objectives: This study aimed to analyze the correlation among dental hygiene students' life stress, grit, and career decisionmaking self-efficacy, and to identify the factors influencing career decision-making self-efficacy. Methods: Data were collected through a survey from October 19 to November 7, 2020, targeting 196 students enrolled in dental hygiene departments in Daejeon and Daegu. Life stress, grit, and career decision-making self-efficacy were measured. For data analysis, the descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and stepwise multiple regression analysis were performed using SPSS/WIN 24.0. Results: Life stress was 2.12 points, grit was 3.07 points, and career decision-making self-efficacy was 3.43 points. Career decision-making self-efficacy was influenced by satisfaction with the course department, as well as life stress and grit; the most influential factor was found to be grit. These variables could explain career decision-making self-efficacy by 23.8%. Conclusions: For students to advance successfully into society as dental hygienists, a career decision-making self-efficacy promotion program that can help students achieve self-confidence and establish career goals should be developed. additionally, a program that can enhance grit should be included in this development.

The purpose of this study is to provide basic data for career guidance to cosmetology students by examining the effects of job stress on career decisions and job preparation behaviors. Overall 214 parts were empirically analyzed as final samples. Collected data and statistical processing are based on SPSS ver. Analysis was performed using the 21.0 program. An analysis of the effect of job stress on career decision showed that employment anxiety (β= .206, p<.05), job anxiety(β=.824, p<.05), and anxiety in career search(β=.118, p<.05) showed a statistically significant effect(+). However, employment concerns(β=-.312, p<.001) in career determination and employment concerns(β=-.223, p<.01) in career search are statistically significant parts(-). An analysis of the effect of employment stress on employment preparation behavior found that employment anxiety(β=.364, p<.05) has a statistically significant effect(+) on information use preparation, It was found that the statistically significant part(-) affects employment anxiety(β=-.188, p<.01). The study found that the more anxious cosmetology students are about employment, the more they plan and explore career options, and make information-based preparations for employment. Through this research, we hope that there will be lively discussions among cosmetology students on career adaptability, life satisfaction, and employment anxiety.

DNA methylation regulations gene expression, thus having pivotal roles in a myriad of physiological and pathological processes. In this study, the morphology and stress tolerance of transgenic rice overexpressing NtROS2a were determined. Transgenic plants exhibited less and shorter lateral shoots. Under various treatments, rice overexpressing NtROS2a showed alleviation of damage symptoms with higher survival rate. After drought and re-watering treatment, transgenic rice seedlings restored their normal growth. However, wild type plants could not be rescued. These findings indicate that overexpression of NtROS2a gene in rice seedlings can increase their tolerance to drought stresses.

Railway point machines act as actuators that provide different routes to trains by driving switchblades from the current position to the opposite one. Since point failure can significantly affect railway operations with potentially disastrous consequences, early stress detection of point machine is critical for monitoring and managing the condition of rail infrastructure. In this paper, we propose a stress detection method for point machine in railway condition monitoring systems using sound data. The system enables extracting sound feature vector subset from audio data with reduced feature dimensions using feature subset selection, and employs support vector machines (SVMs) for early detection of stress anomalies. Experimental results show that the system enables cost-effective detection of stress using a low-cost microphone, with accuracy exceeding 98%.

This is descriptive research aimed at determining the relations with appearance satisfaction and self-efficacy in controlling job-seeking stress and at providing basic data necessary to decide on an education direction for better career maturity and explore psychological resources. For data collection, convenience sampling was performed among dental hygiene students consenting to participate in the research in Chungcheong and Jeolla Provinces to complete a self-administered questionnaire from November 25 to December 13, 2019. Appearance satisfaction was positively correlated with self-efficacy and was negatively correlated with job-seeking stress; self-efficacy was negatively correlated with job-seeking stress. The factors affecting job-seeking stress were self-efficacy, appearance satisfaction, and major satisfaction. It would be necessary to develop a practical counseling program targeting the combination of positive appearance acceptance and improvement in self-efficacy on the basis of correct aesthetic values with the objective of reinforcing job-seeking competence intensively among dental hygiene majors.

This study examined the level of depression according to the characteristics of school and family life of female high school students. In particular, this study attempted to identify the relationship between academic stress and the depression levels. The survey conducted a self-administered questionnaire from 438 students at D city in August, 2019. As a result, the distribution of the depression levels among the study subjects was 78.8 % for 「normal」 and 21.2 % for 「depression」, and the distribution of depression was significantly higher in groups with higher academic stress. The academic stress and depression levels showed significant positive correlations. In logistic regression analysis, the risk ratio of 「depression」was significantly higher in groups with higher academic stress than in groups with lower academic stress. According to multiple regression analysis, the factors affecting the level of depression were chosen as significant variables, such as academic achievement, relationship with school fellow, satisfaction with school life, test stress, study stress, and career stress. The above findings suggest that the level of depression in female high school students was related to academic stress and many other variables of school and family life characteristics.
